Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1-2, the aluminum alloy zigzag-shaped rod node structure according to a preferred embodiment of the present invention includes a node disc assembly 1, a rod assembly 2 and a connecting core 3, wherein the rod assembly 2 is fixedly connected by the node disc assembly 1 and the connecting core 3, respectively. Specifically, the node plate assembly 1 includes a first node plate 11 and a second node plate 12 which are spaced apart in parallel, a first end of the rod assembly 2 is fixedly connected to the first node plate 11 by a first fastening member 41, a second end of the rod assembly 2 is fixedly connected to the second node plate 12 by a second fastening member 42, and a middle portion of the rod assembly 2 is fixedly connected to the connecting core 3 by a third fastening member 43.
As shown in fig. 3, the node plates 11, 12 of the present embodiment are aluminum alloy node plates having three radially outwardly projecting protrusions 1A for connecting the rod assembly 2 (see fig. 1). In particular, two adjacent protrusions 1A are in transition by chamfering. It will be appreciated that the particular orientation and number of the projections 1A of the node plates 11, 12 may be adjusted according to the arrangement of the lever assembly 2.
As shown in fig. 4-5, the bar assembly 2 of the present embodiment comprises three aluminium alloy box bars arranged around a central longitudinal axis, each box bar being a delta bar 21 comprising first and second parallel spaced side panels 2A, 2B, a first flange 2C connecting the first and second side panels 2A, 2B at first ends of the side panels 2A, 2B and a second flange 2D connecting the first and second side panels 2A, 2B at second ends of the side panels 2A, 2B. In particular, the B-shaped bar 21 comprises a web 2E connected perpendicularly between the middle of the first and second flanges 2C, 2D, which is arranged parallel to the first and second side panels 2A, 2B. Referring to fig. 1 and 2, the first flange 2C of each of the rectangular bar members 21 is fixedly connected to the first node plate 11 by a first fastening member 41, the second flange 2D of each of the rectangular bar members 21 is fixedly connected to the second node plate 12 by a second fastening member 42, and the web 2E of each of the rectangular bar members 21 is fixedly connected to the connecting core 3 by a third fastening member 43.
